  1. Past hour
  2. Planetary, start clusters, lunar, etc. should be alright, I agree. Galaxies and nebulae not so.
  3. It is pretty dark Gina, I sat in the garden last night looking at the stars around 11pm and it was pretty decent, maybe AP need conditions to be a lot darker, but on the whole it’s worth a shot
  4. Was it windy by any chance? That's a big scope you've got in your signature. At that focal length you'll really want good polar alignment and good guiding.
  5. Your requirements are contradictory - I suggest refining your requirements or looking at multiple setups. Re the mount: portable means lightweight while suitable for astrophotography means solid and heavy. Nothing wrong with the Meade LX85 AFAIK but I would not have described it as 'lightweight'. I don't have a full spec for it but with 33bs capacity I get the impression it is on the limit of what I would like to drag outdoors and assemble without assistance. What kind of astrophotography? Planetary and deep space have totally different requirements. Re the scope : portable is easily managed (buy a small one), but multipurpose does not work. Deep space astrophotography points to a small high quality refractor, general observing, depending on who you listen to, means any sort of scope (within reason), planetary observing likewise, while planetary astrophotography seems to require the biggest SCT you can afford and get mounted up. The SCTs score on usability - they are shorter and lighter than the equivalent in other designs, the eyepiece remains in a convenient position regardless of where the scope is aimed, and they have a great depth of focal range facilitating the attachment of various accessories.
  6. Thank you so much, Peter. Amazing. Yes, it looked like this: https://www.theverge.com/2019/5/25/18639905/spacex-starlink-satellites-video-dr-marco-langbroek-netherlands although dimmer, as we were observing with the naked eye. Very spectacular. Best regards, Grae
  7. Unfortunately clear skies aren't much good if it doesn't get dark! Not that you can rely on weather forecasts anyway!
  8. Hello and welcome to SGL. What you saw was probably the launch and deployment of the new Starlink satellites by Space-X
  9. Thanks, I do use the Canon camera connect with my DSLR in combination with an intervalometer so best of both like you describe, I find the on screen microfocussing very useful when using camera lenses. Alan
  10. Hi everyone, Last night I started imaging, I took about 30 * 120sec . I tried it without Autoguiding, because my laptop didn't want to wake up . Some of photos were awesome, others were with beginning trails, other with terrible trails. All of them were mixed, I mean after a good shot I got a very bad one and so on... If it was bad polar alignment I wouldn't get any good shots, if it was good , then why I'm getting the bad one? Any ideas why would that come from? Best regards,
  11. Hi folks. I am sorry if this post is not suitable for this forum; I have searched the Internet for somewhere that may be able to help me with this. I am in a remote part of North West France and last night the sky was very clear. At around 12:30am my brother and I saw what looked like a very long, dull beam of light travelling from South West to North East. The beam was observed for approximately two minutes until it disappeared out of view. The luminance did not diminish at any point. What made this even more strange (and not at all like anything associated with an aeroplane) was that within the beam of light were what looked like many twinkling points of light. I liken this to a beam of light capturing dust in the air. There seemed to be three 'leading' points of light that did not twinkle, set apart from each other. There were no streaks of light as seen with meteor showers, and the brightness was consistent. All of the points of light, including the 'leading' points of light looked the same size at the stars. No lights were flashing and there was no noise. It certainly looked like some kind of space-related event. If so, the length of the beam must have been vast. Does anybody have any ideas as to what this could have been? Many thanks.
  12. A question for any electronics gurus, please? I made up a circuit, readily available on the web, using an LM7808 to convert 13.8 volts from either my stabilised mains power supply or from a 12 volt accumulator to 8 volts to use with a Canon dummy battery in my Canon 700d. It worked nicely, delivering 7.9 volts and the camera is quite happy with that. Went to try it out last week and after about 20 minutes or so everything stopped as the 15 amp power supply (which also powers the mount and the camera cooler) cut out. Further investigation showed that the small plastic case in which the LM7808 is mounted with a couple of capacitors on a strip of Veroboard was too hot to touch. So was the supply cable. Investigating with a remote infra red thermometer suggests that the LM7808 reaches 50°C within a minute or so of switching the camera on. I haven't measured the current draw, lacking a suitable spot to break into the supply cable, but guess this might be the problem? If so, is this to be expected when dropping 13.8 v to 7.9 with about (I estimate) a maximum 2 amp demand? I haven't used a heat sink as my hope was to keep everything small and light such that the whole unit could simply hang on the cable. I do have another LM7808 if it is possible that the original is defective, but would appreciate more knowledgeable input before putting my pretty limited desoldering ability to the test.
  13. Hi Dave, welcome to SGL.
  14. The 100mm APO refractor niche seems very well populated with quality scopes. There must be a point where local seeing conditions, mount guiding accuracy and a whole host of other factors just negate the extra £4000 ($4000) that you could spend. eg. I quite fancy some counterweights for my NEQ6 hewn out of Iridium based meteorites, but......
  15. Lets see.....I am about 40 mile north from you...I will try and open my obsy quickly and suck the clouds away from you...
  16. It looks like we are going to have some rain Later in Northants but then a few hours of clear skies are forecast which is especially good because I find the seeing to be better after a nice rainfall. This coupled with no work for a couple of days is all sounding a little to good to be true fingers crossed.
  17. Today
  18. Hi fellow Dave, welcome.
  19. I guess without putting exotic words like Lzos or Lomo in the description as well as another few other high quality marques the Espirit range seem to take a bit of beating from what I have read and have seen results from and even here SW's offering would be so close to these as to barely matter. I did have here for a while a 90mm APO triplet from Telescope Services that performed very nicely, I very nearly bought one 5 years back, I believe it was F6. That said owning a APM larger scope I would go for the 100mm Espirit, fast and wide enough, if I were to buy tomorrow.
  20. One Celestron TrailSeeker 65 Straight Spotting Scope. Open Box Complete with full manufacturer's UK warranty. £179.00 £149.00 (saving £30.00)
  21. If you do that it's bound to be cloudy tonight!!
  22. Champagne bubbles?. I'm a posh astronomer.
  23. I did this with a twin Samyang setup and Asi cameras. You can open 2 instances of Sgpro. Richard.
  24. After setting up the Macro using the desired wavelet settings go to add files. It won't show image files only video type files. To overcome that just go to the folder with your tifs and enter *.* in the file name and you will see your tif images. Highlight all of the tifs and click OPEN. Now the batch will run against all of your images. Make sure you select a different file format for the wavelet save otherwise it will overwrite the original tifs. Ben Loyola
